The "Stronger (What Doesn't Kill You)" singer looks breathtaking in the photo, in which she's sitting in a windowsill, surrounded by bookshelves, casually reading. But she's wearing a stunning wedding dress. The gown features a sweetheart neck and spaghetti straps, and has a full skirt with layers upon layers of fluffy fabric. Her wavy hair is loosely styled up and she is wearing a dainty headpiece.

In other words, she looks like a princess.

Our favorite part of the photo, however, is that she's barefoot. Her feet are just hanging down beneath the tulle. It's very Kelly.

The cover art for Kelly's single

This is the second bridal look we've seen from the star in recent months. In June, she released her single "Tie It Up," which is a song about getting hitched, and is dressed like a bride in the cover art. But it's a much different look ― her hair is down and she's wearing a big veil. The wedding dress she's sporting has a high neck and is lacy — its not as soft and dainty as the one we see in her engagement shoot.

The singer will reportedly marry music manager Brandon Blackstock October 20 in Nashville, where she relocated full-time after they started dating in 2011. We can't wait to see her wedding photos from the big day. After a few trial runs (one more stunning than the next), she's going to be sheer perfection on her big day.

Not that we would expect anything less.
